Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each chemical. The data was averaged

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

Title: The Mass of Quartz Purpose: To determine the density slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of
